Find LCM of 220,540,981,237,790 with Prime Factorization
| 2 | 220, 540, 981, 237, 790 |
| 2 | 110, 270, 981, 237, 395 |
| 3 | 55, 135, 981, 237, 395 |
| 3 | 55, 45, 327, 79, 395 |
| 5 | 55, 15, 109, 79, 395 |
| 79 | 11, 3, 109, 79, 79 |
| 11, 3, 109, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 79 x 11 x 3 x 109 x 1 x 1 = 51149340
Therefore, the lowest common multiple of 220,540,981,237,790 is 51149340.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
220 x 540 x 981 x 237 x 790 = 21820308444000
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
981 : 1, 3, 9, 109, 327, 981
237 : 1, 3, 79, 237
790 : 1, 2, 5, 10, 79, 158, 395, 790
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,540,981,237,790, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
540:2x 2x 3x 3x 3x 5
981:3x 3x 109
237:3x 79
790:2x 5x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 3x 3x 5x 5x 79 = 426600
Therefore, the value for common factors is 426600.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 21820308444000/(1x426600)
LCM = 21820308444000/426600
LCM = 51149340
Thus, we can understand that the LCM of 220,540,981,237,790 is 51149340.
